ISR Performance Intake Kit - RB25DET

Our intake kit for the RB25DET when swapped into a 240SX S13 or S14 chassis using our ISR swap mounts. Designed around the factory RB25 turbo location and the routing constraints of the S-chassis engine bay, so the intake clears the chassis without requiring you to fabricate something custom.

What It Does

Provides a bolt-on intake path from the factory RB25 turbo inlet to a high-flow bolt-on air filter, routed cleanly through the S-chassis engine bay. The aluminum intake pipe is sized to support the airflow the factory RB25 turbo needs, and the included T-bolt clamps and silicone couplers keep everything sealed under boost.

Fitment

Fits the Nissan 240SX (S13 and S14) running an RB25DET swap with the factory RB25 turbo and ISR Performance swap mounts.
